316L pipes with reducers and flanges

304 Piping Spools are made of 304 Stainless Steel, a common and popular material in many industrial applications that require resistance to corrosion and oxidation. These S30400 Piping Spools are prefabricated using specialized machinery and processes, which ensure that they are highly accurate and reliable.

INCONEL 718 alloy was primarily chosen by design engineers for its high strength in extreme temperature conditions at both ends of the spectrum. It can be used from low temperatures all the way up to 1300¡ãF/704¡ãC. It exhibits extremely high yield, tensile and creep rupture properties across the entire range. It also exhibits excellent tensile and impact strength.

Alloy 254 SMO is a high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content.

Alloy 347 (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100).

Nickel- and cobalt-based corrosion-, temperature- and wear-resistant alloys, such as Hastelloy B2, are classified as moderate to difficult when machined, but it should be emphasized that these alloys can be produced at satisfactory speeds using conventional production methods processing. During machining, these alloys harden rapidly, generate high heat during cutting, weld to the cutting tool surface, and provide high resistance to metal removal due to their high shear strength.

Incoloy 800/800H/800HT are solid solution nickel chromium iron alloys with small additions of aluminium and titanium to improve corrosion and oxidation resistance.

In pressurized water reactors it is used for control rod guide tubes and steam generator baffle plates etc. Furnace retort seals, fans and fixtures.

Alloy 400/Monel 400 comes directly from refined ore bodies in Canada, and with a copper content of approximately 30 wt%, it provides a lower cost alternative to commercially pure nickel, but still retains a very similar characteristics.

The Alloy 800 series (Incoloy 800, 800H and 800HT) are nickel-iron-chromium superalloys that provide high temperature strength and resistance to oxidation, carburization and other types of high temperature corrosion. Alloy 800 (UNS N08800), Alloy 800H (UNS N08810) and Alloy 800HT (UNS N08811) have the same nickel, chromium and iron content, except for the total titanium and aluminium content (0.85 to 1.2%) to ensure optimum high temperature performance.

However, their fatigue strength is higher than the slip-on flanges. A major problem of the socket weld flanges is the corrosion risk. A gap between the flange and fitting or pipe must be maintained before the welding. Corrosive fluids or humidity can locate in these shelters. Thus, this solid-liquid interface may cause corrosion on the body.

It is known to possess excellent workability as well.

HastelloyB2 is a nickel-based wrought alloy with excellent resistance to hydrochloric acid at all concentrations and temperatures. Therefore, it has strong resistance to stress corrosion cracking and pitting corrosion. It is also resistant to hydrogen chloride, sulfuric acid, acetic acid and phosphoric acid. Hastelloy B-2 is a grade of Hastelloy?, a nickel-molybdenum alloy. There are many different grades of Hastelloy?, including B-2. Hastelloy? grades are optimized for specific applications. molybdenum

Alloy 904L outperforms other austenitic stainless steels due to the higher degree of alloying of nickel and molybdenum.

The addition of copper to this grade gives it better corrosion resistance than conventional chromium-nickel stainless steels, especially against sulfuric, phosphoric and acetic acids. However, the use of hydrochloric acid is limited.

The durability of steel is one of the best advantages of the pipeline systems. It is strong and it can withstand the pressures, temperatures, heavy shocks, and vibrations. It also has unique flexibility which provides an easy extension.

The tees are also used for the change of the flow angle and distribution of the flowing matter either into one or more channels. Tees can be divided into two main groups which are the butt welded tees and the socket welded tees. The butt welded tees are utilized to perform a perpendicular distribution of the flow. They make 90¡ã branches with the connection of the pipeline and distribute the coming matter from the mainline.

Prefabrication can be of many different types and undertaken at many different scales, from fabrication of small components and sub-assemblies through to large welded and bolted assemblies requiring significant logistical challenge to transport to site

Virtually immune to chlorine ion stress corrosion cracking. Demonstrates adequate resistance to organic acids such as acetic, formic and stearic. Excellent resistance to high purity water used in primary and secondary circuits of pressurized nuclear reactors.

Reworking of Alloy K-500 is best done while the material is in the annealed or hot worked and quenched condition. However, age hardened materials can be finished to close tolerances and finish. Therefore, the recommended practice is to machine slightly oversize, age harden, and then finish to size.

Alloy 625 has excellent fatigue strength and stress corrosion cracking resistance to chloride ions. This nickel alloy has excellent weldability and is often used to weld AL-6XN. This alloy is resistant to a variety of severe corrosive environments, especially pitting and crevice corrosion.

Alloy K500 is refined by Electroslag Refining (ESR), ensuring the cleanest and highest quality material. This increased alloy purity limits the potential for hard non-metallic inclusions that can increase machining difficulty, machining time and ultimately lead to part failure. It also has low permeability and is non-magnetic at temperatures as low as -150¡ãF (-101¡ãC).

It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 ¨C 1500¡ãF (427 ¨C 816¡ãC).?

Steel Pipe Spools are also referred as prefabricated components of a piping system such as pipes, flanges and pipe fittings, and they are mounted during the development before sending them to the manufacture.

Alloy 800 has moderate corrosion resistance to many aqueous media and is resistant to stress corrosion cracking due to its nickel content. At high temperatures, it has resistance to oxidation, carburization and vulcanization as well as fracture and creep strength.

Inconel is a superalloy made of high concentrations of nickel, chromium and molybdenum. Inconel 625 is highly resistant to corrosive and oxidizing media in a variety of environments. These alloys have excellent ductility and excellent formability. They can be welded easily and are resistant to post-weld carburization or graining.

Monel 400 is a nickel-copper alloy (about 67% Ni ¨C 23% Cu) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions.

Prefabrication is the practice of assembling components of a structure in a workshop or other assembly facility before transporting to site for erection.

The pipe spools are usually applied in concrete structures to make sure the necessary fittings are in place before pouring concrete into the construction.

A fit-up and welding process must be applied after the edge finish of the parts. Therefore, for stainless steel and carbon steel pipe spools, parts can be located onto steel bases or wooden bases. Furthermore, any contact possibility between carbon steel and stainless steel must be minimized.
